Cut the chicken breast into bite-sized 1-inch cubes and place them in a small bowl.
Toss the chicken cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small glass jar, whisk together the orange juice, orange zest, coconut aminos, honey, grated ginger, and minced garlic to create the glaze.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet in a single layer and sear for 3-4 minutes per side until golden brown and crispy.
While the chicken cooks, steam the broccoli florets in a separate pot for 4 minutes until tender-crisp.
Pour the orange glaze mixture into the skillet with the chicken and simmer for 2-3 minutes until the sauce thickens and coats the chicken beautifully.
Serve the crispy orange chicken over the steamed broccoli and garnish with sesame seeds.
